スキャフォールドを生成した直後に、新しいテスト ダミー データを作成しようとすると NoMethodError が発生します。
私はレールに慣れていないので、おそらく単純な間違いをしているのでしょうが、レールが最初からエラーのあるファイルを生成する必要があったようには見えません。
モデル:
class Character < ActiveRecord::Base
attr_accessible :cha, :class, :class_option, :con, :dex, :exp, :int, :name, :portrait_url, :str, :wis
end
意見:
<h1>Listing characters</h1>
<table>
<tr>
<th>Name</th>
<th>Exp</th>
<th>Class</th>
<th>Class option</th>
<th>Str</th>
<th>Dex</th>
<th>Con</th>
<th>Int</th>
<th>Wis</th>
<th>Cha</th>
<th>Portrait url</th>
<th></th>
<th></th>
<th></th>
</tr>
<% @characters.each do |character| %>
<tr>
<td><%= character.name %></td>
<td><%= character.exp %></td>
<td><%= character.class %></td>
<td><%= character.class_option %></td>
<td><%= character.str %></td>
<td><%= character.dex %></td>
